The DBH 9891Vit radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain oil or grease and exclude dust and water. Its dimensions of 22.00 mm shaft, 45.00 mm housing and 8.00 mm height place it in small and medium-sized equipment. It is a wear part: when the lip hardens or the shaft marks a track, it should be replaced to avoid leaks and lubricant loss.

This item is a DBH 9891Vit radial shaft seal, identified by its designation 9891Vit, with the following dimensions: shaft diameter 22 mm, housing diameter 45 mm and height 8.00 mm. The indicated design is Lx-R H, which corresponds to a single-lip seal with spring and metal body, suitable for rotating shafts. The sealing lip works on the shaft and the outer diameter fits by interference in the housing. The 8.00 mm height defines the width of the housing where the seal must fit.

Typical applications for a seal of these dimensions include small gearboxes, centrifugal pumps, electric motors, compressors, mixers and transmission equipment where lubricant must be contained and contaminants kept out. It is also used on fan shafts, agitators and machine tools. In all cases, the seal protects the bearings and the lubricant from the environment, and its correct installation extends the service life of the assembly.

To select and install this seal, check that the shaft diameter is within the recommended tolerance and that the contact surface is polished and free of burrs. The housing must have the appropriate diameter and depth for the 8.00 mm height, with an entry chamfer so as not to damage the lip. Lubricate the lip before installing and use an installation tool that presses on the outside of the seal, never on the lip. If the shaft shows wear, consider a repair sleeve.
